BURNING-PRESS.

Legame.

T0 @ZZ whom, fit may concern Be it known that l, HENRY L. KOEHLER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Burning-Presses, of which the following is a specification.

lThis invention relates to burning presses, the object in view being to provide a. rotary press which will quickly and effectively burn letters, monograms, designs, and printed matter of all descriptions on any kind of wood, liber, card-board, or various kinds of material of any thickness, the machine embodying means for keeping in a properly heated condition a cylindrical or segmental form bearing the type, letters, designs, monograms, etc., to be burned into the material referred to.

A further object is to provide means for regulating the .area of the flame used for heatingl the type form; also means for gaging the position of the work and the delivery of the same to the burning cylinder.

A further object of the invention is to provide novel and effective means for intermittently feeding the boards or other form of work to the burning cylinder at the proper period of time, to cause the impression to be made on the board in proper relation to the margins thereof.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended. y

Fig. 9 is a side elevation of one of the central disks or supports for the tubular burners. Fig. 10 is a side elevation of the gas manifolds of the burning cylinder, showing the arrangement of stop cocks therefor. Fig. 11 is a detail section through one-half of the same, showing one of the manifolds and the parts connected therewith. Fig. 12 is a detail section showing the driving mechanism for the impression roller. Fig. 13 is a vertical fore and aft section showing the manner in which the work table is supported.

The rotary burning machine contemplated in this invention embodies a suitable frame for supporting the operative elements of the machine, and in the preferred embodiment thereof, this frame consists of the two side members 1 and 2 which are provided with suitable flanges 3 adapted to receive lag screws for bolting the machine frame as a who-le to the floor. The side frame pieces 1 and 2 are alsol connected by cross tie bolts 4, any number of which may be employed. Mounted in bearings 5 in the upper portion of the frame pieces 1 and 2 is the main burning cylinder shaft 6, the same being held in place by cap pieces 7 secured by bolts 8.

The burning cylinder comprises two oppositely arranged heads or disk-shaped supports 9, the hubs 10 of which are fast on the shaft, and in addition thereto several intermediate 0r central disk-shaped supports 11. Each of these supporting members 9 and 11, all of which are fast on the shaft 6, is provided with an annular series of holes 12, which receive a corresponding number of tubular burners 13. Each of said burners consists of ya tubing of suitable length, provided throughout the length thereof with any desired number of perforations of suitable size, through which the vapor escapes, and is ignited so as to form a practically continuous flame which operates against the inner surface of the type form, hereinafter referred to. The members 11 are also perforated at 13 to allow the heat to pass through them. Each of said tubular burners'is closed at one end, as shown at 14e, and provided at such end with means for turning the same on its longitudinal axis, the means shown consisting of a screw driver notch 15. At its opposite end, each tubular burner 2 is threaded as shown at 16, and screwed into an internally threaded opening in a manifold 17.

By now. referring to Fig. 10, it will be Vseen that I employ a circular series of'manifolds 17, to each of which a certain number of tubular burners 13 is connected. Ea-ch manifold 17 is provided with an inwardly extending radial feed pipe 18 which communicates with a central longitudinal bore 19 in the shaft 6, as shown in Fig. 3. Each feed pipe 18 is also provided with an individual stop cockV 20, so that the supply of gas may be cut off therefrom, when a form less than a complete cylinder isemployed.

The type form shown at 21 is in the form Aof a hollow cylinder or segment of a cylinder, and the opposite edges thereof are; .chamfered, as shown at 22, so as to be enl gaged by oppositely arranged sets of clamps 23, each provided with a V-shaped notch 24 to engage one end of the type form. Each of the clamps 23 is also provided with an internally threaded opening 25 to receive a threaded adjusting or clamsping .screw 26, one end of which is squared, as shown at 27, to enable the same to be turned with the aid of a suitable wrench. Each screw 26 is proe vided at its opposite ends with reduced j ournal portions 28 which `are received in holes 29 and 30 in the intermediate and end supports 11 and 9 of the burning cylinder, as

indicated in Fig. 3.' Screws 30 are also inserted through the form 21 into the supports 11 as shown in Fig. 3.

From the foregoing description, it will be seen that the burning cylinder is made up of a circular series of tubular burners, and that the type form is in the form of a hollow cylindrical sheet which extends around. and is supported outside of said tubular burners, and is held in place by screws and oppositely arranged sets of sliding clamps which are moved toward and away from the chamfered edges of the form by means of adjusting or clamping screws. r

The radial feed pipes 18 of the manifolds 17 all enter a common box or hollow distributing collar 31, at opposite sides of which are arranged stufng boxes 32 and 33 to provide a gas-tight joint between said pipes 18 and the shaft 6. Gas, gasolene, or other f vapor or oil may be fed through the hollow bore of the shaft 6 from any source of supply, and by means of any suitable connection, the gas passing thro-ugh holes 33 in the shaft 6 into the distributing collar 31, and thence through the pipes 18 to the manifolds 17 and burners 13.

Arranged directly beneath the burning cylinder is an impression roller 34 mounted loose on the shaft 35 supported in bearing boxes 36, which are slidable up and down in guide ways 37 between parallel guide ribs 43 designates the work supporting table Y which is provided with parallel grooves 44, in the upper face thereof, adapted to guide a pair of parallel feed chains 45 provided with oppositely arranged sets of detachable and adjustable teeth 46 forming projecting shoulders adapted to engage the rear edge of aboard or piece of wo-rk, so as to advance the work to the burning cylinder... These ychains 45 pass around wheels 46set.into`.the

impression roller 34, as shown'in Fig. 3, and at their opposite ends. are passed around wheels 47 on a shaft 48 journaled in bracket arms. 49 which are 'adjustable Vinand out relatively to the frame of the machine, .as showirin Fig. 1, each of said bracket arms being provided with a Ylaterally.extending lug 50 which receives an adjusting screw 51 impinging at its inner end against the frame. This enables the chains to be tightened, so

that they will accurately feed the work in# ward to the burning cylinder. Each bracket arm 49 is held fast by a binding screw or bolt 52 passing through a horizontal slot 53 in 'the machine frame, thereby enabling the operator to fix the adjustment `of the bracket arms. The table 43 is also provided with the laterally extending slots 54 adapted to receive flanges 55 on the'bottoms of a vpair of sliding brackets or arms 56, each of which is provided with a broad base 57 which rests Y on and slides in contact with the upper surface of the table. Secured to each pair of bracket arms 56 is a yface plate 58 which forms one of the side gages, between which the sheets or boards are placed, preparatory to their being fed inwardly one at a time and submitted to the action of the burning cylinders. The arms or brackets 56 are further provided with holes to Vreceive clamping screws 59 which pass throughthe slots 54 in the table, and are tightened by means of thumb nuts 6() for fixing the adjustment of the 'lateral gages. Thearms or brackets 56 are further provided withholes 61 adapted to receive bolts 62 which pass through slots` sheet of material being operated upon, the idea being that when the bottom board or sheet of the pile is allowed to pass under the gage plate 64, the remainder of the pile or stack being restrained and held back by said plate, which thus acts as a cutoff.

Near its front edge, the table 43 is provided on its under side with knuckles 65, through which passes one of the tie bolts or rods 4 forming a pivotal support for that edge of the table. At its inner edge, the table is provided with forks 66 which embrace the shaft 35 of the impression roller and support such edge of the table thereon, so that it rises and falls with the impression roller, in accordance with the thickness of the work being fed to the burning cylinder.

The driving shaft 67 is journaled at one end in the machine frame, and at its other end in a bracket 68 projecting from the frame, and is shown equipped with a cone pulley 69 to provide for variable speed. A spur pinion 70 fast on the shaft 67 drives a large gear wheel 7l on the shaft 6 of the burning cylinder, and also drives a pinion 7 2 on a short hollow shaft or sleeve 7 3 supported by a stud shaft 74 projecting outwardly from the machine frame, as in Fig. 3. Fast on the same sleeve or shaft 7 3 is a sprocket wheel 75, from which a chain 76 extends around another sprocket wheel 77 fast on the end of the shaft 48 which drives the feed chains 45. By the mechanism just described, motion is imparted to the burning cylinder and feed chains, and the impression roller is permitted to move toward and away from the burning cylinder.

Where the type form is less than an entire hollow cylinder, it will be apparent that by means of the stop cocks 20, one or more of the manifolds 17 may be cut out and consequently the tubular burners 13 which are supplied by said manifolds. The burning cylinder is therefore adaptable to forms of widely varying sizes.
